SQL*Loader : ORA-19007 with missing Schema Location Hint

Question

Hi,
These days I'm stuck with a 10.1.0.4 database (OS Linux Red Hat), and I'm trying to find a workaround for the following situation :
XML schema (sfgtest.xsd)
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:xdb="http://xmlns.oracle.com/xdb">

    <xs:simpleType>
      <xs:restriction base="xs:string">
        <xs:maxLength value="16"/>
      </xs:restriction>
    </xs:simpleType>
  </xs:element>
  <xs:element name="Val" xdb:SQLType="NUMBER" xdb:SQLName="Val">
    <xs:simpleType>
      <xs:restriction base="xs:decimal">

      </xs:restriction>
    </xs:simpleType>
  </xs:element>
  <xs:element name="Chq">
    <xs:complexType xdb:SQLType="SFG_CHQ_TYPE">
      <xs:sequence>
        <xs:element ref="Code"/>
        <xs:element ref="Val"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="NbRem" xdb:SQLType="NUMBER" xdb:SQLName="NbRem">
    <xs:simpleType>
      <xs:restriction base="xs:integer">
        <xs:totalDigits value="5"/>
      </xs:restriction>
    </xs:simpleType>
  </xs:element>
  <xs:element name="Rmbt" xdb:defaultTable="TEST_XML_SFG">
    <xs:complexType xdb:SQLType="SFG_RMBT_TYPE">
      <xs:sequence>
        <xs:element ref="NbRem"/>
        <xs:element ref="Rem" maxOccurs="unbounded" xdb:SQLCollType="SFG_REM_COLL"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="CodeAff" xdb:SQLName="CodeAff" xdb:SQLType="VARCHAR2">
    <xs:simpleType>
      <xs:restriction base="xs:string">
        <xs:maxLength value="12"/>
      </xs:restriction>

        <xs:element ref="Chq" maxOccurs="unbounded" xdb:SQLCollType="SFG_CHQ_COLL"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>
Sample document (sfgtest.xml)
<?xml version="1.0" encoding="iso-8859-1"?>
<Rmbt>
<NbRem>3</NbRem>
<Rem>
  <CodeAff>AFF001</CodeAff>
  <Chq><Code>X01001</Code><Val>10.00</Val></Chq>

</Rmbt>
Schema registration
begin
dbms_xmlschema.registerSchema(
schemaURL => 'sfgtest.xsd',
schemaDoc => xmltype(bfilename('DUMP_DIR','sfgtest.xsd'),nls_charset_id('AL32UTF8')),
local => true,
genTypes => true,
genTables => false
end;
Table creation
create table test_xml_sfg of xmltype
xmltype store as object relational
xmlschema "sfgtest.xsd"
element "Rmbt"
varray xmldata."Rem" store as table test_xml_sfg_rem_tab
( primary key (NESTED_TABLE_ID, ARRAY_INDEX) ) organization index overflow
varray "Chq" store as table test_xml_sfg_chq_tab
  ( primary key (NESTED_TABLE_ID, ARRAY_INDEX) ) organization index overflow
);I originally wanted to use SQL*Loader to test performance, as I may have to load multiple files in the same time.
It works great on 10gR2 and 11gR2 with XML files up to 100 MB loaded in a matter of minutes.
However, a little issue with 10gR1 :
SQLLDR control file
LOAD DATA
INFILE 'filelist.txt'
APPEND
INTO TABLE test_xml_sfg
XMLTYPE(XMLDATA) (
filename filler char(260),
XMLDATA LOBFILE(filename) TERMINATED BY EOF
)with filelist.txt :
sfgtest.xmlExecution throws "ORA-19007: Schema - does not match expected sfgtest.xsd".
As per the documentation, it's expected behaviour in 10.1 :
http://download.oracle.com/docs/cd/B14117_01/appdev.101/b10790/xdb03usg.htm#BABECCBG
The XML document must include the appropriate attributes from the XMLSchema-instance namespace or the XML document must be explicitly associated with the XML schema using the XMLType constructor or the createSchemaBasedXML() method.Also as expected, the file is loaded OK after adding the following in the root element :
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="sfgtest.xsd"But, as I don't have any latitude on the files received (i.e. I can't add the location hint), is there some workaround, when using SQL*Loader, to treat the XML file as an instance document?
Thanks for any solution/idea.

Answer 1

Not sure if it will work, but out of the top of my head I would make an attempt to create an view (for update) based on the XMLType table and do the insert via the view, matching the incoming XML doc to the schema via
xmltype(xml_messsage).createSchemaBasedXML(xml_schema)
